The Long timeline is based on an extra 3-4 year period that occurs between the events of the end of QFG2/QFG3 and the beginning of QFG4 that appears in canonical material including in the QFG4 Hintbook (Mordavia History of Events: A Time Line and Who's Who in Mordavia), and in a few in game references in the last two games in the series (which causes a paradox, anachronism or discrepancy in the timeline).
